Traditional Chinese medicine (TCM)
Regulated use of Chinese medicine treatment protocols is included as an exposure factor. Exposure is defined as taking the medication continuously for more than 3 months per year, or intermittently for more than 6 months per year. According to the standardised use of TCM protocols, the group is divided into an exposed group (TCM cohort) and an unexposed group (non-TCM cohort).
Non-traditional Chinese medicine (non-TCM)
All intervention measures that do not meet the criteria for TCM exposure are regarded as non-TCM exposure.
